| Abstract: | A new set of dominance relation is introduced into the interval sets of gray information systems. Concepts such as gray of the object, the degree of certainty towards the object, the overall gray and the overall degree of certainty are defined. A rough set model is presented based on the relationship of dominance, based on which a series of related properties and theorems can be harvested. Finally, an illustrate example is discussed. |
